Answer:
Step-by-step explanation:
10) r + 4/4 = 4
=> r + 4 = 4*4 (by transposing)
=> r + 4 = 16
=> r = 16 - 4
=> r = 12
11) -3 = -4 + q/7
=> -3*7 = -4 + q (by transposing)
=> -21 = -4 + q
=> -21 + 4 = q
=> -17 = q
14) Let the number be x
x/3 + 3 = 9
=> x/3 = 9 - 3
=> x/3 = 6
=> x = 6*3 (by transposing)
=> x = 18
16) Let the number be x
-3 + x/7 = -2
=> -3 + x = -2*7 (by transposing)
=> -3 + x = -14
=> x = -14 + 3
=> x = -11
Hope you understood!!
